PUMP.

SPECIFICATION forming part of Letters Patent No. 242,289, dated. May 31, 1881. Application filed April 23, 1880. (Model) To all whom it may concern:

Be it known that I, Dr. ORLANDO M. FAR- RINGTON, of the city of W'inona, in the county of Winona, State of Minnesota, have invented a new and Improved Method of Constructing a Submerged \Vell-Pump 5 and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

Myinvention relates to certain improvements in the construction of pumps, which render them alike applicable to the driven-well system and that in which the operating parts are submerged.

In my drawings, Figure l is a vertical central section of the pump complete. Fig. 2 is a plan or top view of the lower or hinged valve.

Similar reference-letters indicate like parts in both figures.

Referrin g to drawings, 2 is apipe or cylinder,

which may be of an y required length, extending within easy reach of the delivery-point.

3 is a second cylinder, screw-threaded at a, top and bottom, and adapted for attachment to correspondingly screw-threaded portions of tubes 2 and 4 and plug 0. This cylinder is practically a coupling-sleeve to connect the upper and lower portionsof the pump, and need not be larger than ordinary couplings provided for the trade.

0 is aperforated screw-threaded plug, adap ted to fit snugly into the lower opening of the cylinder 3. It is cut away annular] y to receive a perforated or wire gauze, 7, which, when in place, is held firmly between said plug O and aperforated cylinder, 4, which incases it. The gauze or perforated cylinder 7 is in the form of a cup, and is somewhat shorter than said cylinder which incases it. The cylinder 4, con.- pled to tube 3 by screw-threads, as described, is perforated with holes I) considerably larger than the meshes of the cup-shaped cylinder 7, but too small to admit any matter that would interfere seriously with the said gauze or perforated cylinder, and therefore serves as a protection to it. At thelower end of cylinder 4 is a solid terminal point,f, so fashioned as to fit at its upper end within the cylinder 4, and affording an annular projection outside of said cylinder, and hence serving as a shield against stones and hard lumps in the progress of the tubing downward when being driven to form a well. The point f is securely fastened to the tube 4 by'suitable rivets, which pass through the lower end of tube 4 and the part of the pointf set within said tube. Between the upper part of pointf and the gauze or perforated cup is a space, into which the water flows under said cup and up through the meshes or perforations, so that while water is being lifted the capacity of the openings 1) b will be but little greater than the openings of the perforated cup, although much larger. Within this cup 7 I provide a spiral spring, h, which, when held between the bottom of said cup and the lower surface of plug 0, exerts a force against the vertical walls outward, to assist in resisting any outer pressure coming against said cup through openings 1) in cylinder 4.

On top of plug O is a valve, 5, enlarged at d to give it preponderating weight, to cause it to close quickly when relieved from the pressure of water from below. It is provided with a leather plate, (I, which packs said valve closely to its sent. This valve is hinged between lugs i 2', secured to plug O.

Gr is a piston, of a conical or cup shape, provided with one or more elongated openings and a screw-threaded thimble, j, provided with an openingand adapted to screw into the upper portion of said piston from below. Aball, K, in its normal position, has its seat within the opening in said thimble, and forms a valve which may be lifted by pressure of Water as it makes its way through said elongated openings in said piston. A rod,c, is secured to the piston b and extends within easy reach of the operator of the pump.

From the above description it will be seen that the tubing forming the shell of my pump is composed of three pieces, the terminal point being considered a part of the lower perforated section. In putting the several parts together I first place the gauze cup 7 within the tube4 and clamp it to its place after inserting the spiral spring within said cup. I now screw the coupling 3 down onto the plug O and tube 4. The piston is now inserted, and finally the upper tube is screwed down within said coupling.

Having thus described my invention, what I claim as new, and desire to secure by Letters 2. The combination of tube 4, cup 7 plug 0,
